For the circuit shown in the figure:
A. The current I through the battery is 7.5mA.
B. The potential difference across RL is 18V.
C. Ratio of powers dissipated in R1 and R2 is 3.
D. If R1 and R2 are interchanged, magnitude of the power dissipated in RL will decrease by a factor of 9.
The Correct Answer is: both A and D
The Solution
Now we interchange between the resistors R1 and R2
